PORTABLE X-RAY APPARATUS.

Application filed June 6,

The object of my invention is a portable allkinds of rays used forelectro-therapeutic treatments are produced or generated includingX-rays, and high frequency currents in order to allow their use withfaradization, salvanisation, galvanization, cathaphoresis, electrolysis,caustic treatments, endoscopy, lightand thermo-therapeutics and alsowith the generation of ozone, etc.

Another object of my invention is the provision of an apparatus of thiskind which in compact arrangement contains all the apparatus andcircuits necessary for the above named electromedical purposes.

A- fu'rther object of my invention is the provision of an apparatus ofthis kind in which means are provided for preventing the formation ofarch lights by the arrangement of specially welded wolfram contacts. Astill further object of the invention is the provisionof such anapparatus which is equipped with special means for allowing a i arevertical support of the Tesla transformer adapted to receive the X-raytube allowing a-convenient foldingof the same against the bottom of theapparatus casing when notinuse.

These and other objects of my invention willbecome more fully knownasthedescription of the same proceeds, and will then be specificallypointed out in the appended claim.

In the accompanying drawings forming a material part of this disclosure:Figure 1 is a diagrammatic view illustrating the arrangement of thevarious instru- V ments within the novel electro-medical hand apparatusconstructed according to my invention.

Figure 2 is a top plan view of my apparatus, open. a

Figure 3 is a side view of my apparatus partly in section; h

In the diagrammatic illustration of the apparatus in Figure 1, 1Odesignates the electric socket by means of which the apparatusi can beattached to any electric light circuit.

A switch 11 is provided in the primary circuit 12 so that according tothe position of this switch, 110 or 220 voltage may be used. Aselectorswitch 13 is located behind the switch in order to-allow aselective connectionof the primary circuit to a plurality 1923. SerialNo. 643,744.

of circuits accordingto the specific use of the apparatus desired in thevarious treatments.

1. Use as X-my apparatus.

If the apparatus shall be used for the generationof X-rays or highfrequency cur rents, the selector is switched to make connection withcontact 14.

The conductor wire 15 connected with this contact 14, leads to aninduction coil 16 with an interrupter or circuit breaker 17 the wolframcontacts of which are strongly heat dispensing, and prevent theformation of an arc, in order to ensure the formation of actinic sparksor raysand therewith a high efticiency'of the oscillation circuitarranged parallel to the circuit breaker. v y

This oscillation circuit comprises the magnetically and galvanic' allycoupled Tesla transformer 18 and condensers 19,the' capacity of whichcanbe regulated by means of the two switches 20.

The return circuit Wire for the primary current is designated, 21;, anda current meter 31 is arranged'in shunt therewith.

'An X-ray tube 23 is connected with the secondary circuit of the Teslatransformer 18 over a regulable spark gap 24, and is operated by meansof highfrequency currents by means of the well known circuit. The tubeis attached to two suitable holders secured to the casing of theapparatus.

The intensity of the raysis strong enough to permit the mal'ring ofRontgen pictures besides permitting therapeuticaltreatments and also theillumination for the ascertainment of bone fractures and the discoveryofforeignbodies. The apportioning and control of the ray intensity iseffected by means of a meter in the primary circuit and by means of theregulable capacity and regulable' spark gap 24.

2. Generation of high. frequency currents.

ably held in eyes 62 secured to the bottom plate of the casing and itsupstanding brackets are adapted to engage suitable openings in thebottom plate 63 of the Tesla-transh galvanization. iiii W V 77 y 7 a Theplate for meter 60 carries two pins 67, 68 for attachment of the slottedfoot plate of the post for the mirror or reflector 44which can also,when the mirror is not used, carry a knob for establishing a spark gapbetween its knob and knob 69 on the Tesla transformer, which is alsoremovable for the attachment of a comb if the instrument is used forozonizing purposes as described.

What I claim as new, and desire to protect by Letters Patent is:

In a portable X-ray apparatus of the class described, a Teslatransformer, a casing for said transformer, including a perforatedbottom plate, a U-bracket movably secured to the bottom plate of saidapparatus and adapted to engage with its free arms the perforations insaid bottom plate, and a pin in said bottom plate journaled within theapparatus for allowing a foldin of said transformer against the bottom 0said apparatus when not in use.

In testimony whereof I have atfixed my signature.

WILHELM FALKENBERG.
